The estimated mean lifespan ranges between 13 and 20 years. In one study, it was found that a median lifespan value is 14 years and an interquartile range of 9 to 17 years. Maximum lifespan ranges from 22 to 30 years, but there are some claims of cats living longer than 30 years.
The indoor and outdoor environment also matter. Indoor cats usually live longer than outdoor cats because they are given a good diet and care. The life expectancy also varies in different breeds.
When a cat becomes four months older, it reaches sexual maturity. Meanwhile, a four-month-old cat can get pregnant. The process of having kittens is known as queening. In spring, reproduction becomes fast, and a queen can go to heat every 2 to 3 weeks. The pregnancy of a cat lasts 63 to 65 days.
At 27 years, a cat is 124 years old in human years.
Calculation:
First year of a cat's life = 15 human years
Second year: 9 human years
For the remaining 25 cat years to human years = 25 * 4 = 100 human years
Adding these together:
15 (first year) + 9 (second year) + 100 (remaining years) = 124 human years
